When Chuck Shurley first showed up in the fourth season ofSupernatural, he was just a writer.
Cut to season 5 and speculation began that Chuck (played byRob Benedict) was more than a prophet.
Chuck is God (and also he has a sister).

ENTERTAINMENT WEEKLY: What was your reaction to finding out God would be the series' final villain?
[Laughs] Because when you cross the Winchesters, that’s bad news.
And after this long run, it’s great to be such a big part of the final season.
There’s nothing more epic than the big bad being God.
Did you have to rethink the character after you read that script?
Strict father or crazy showrunner, one of the two.
He’s a fairly subtle villain, for the most part.
You want to keep that idea that we actually have not seen God go off yet.
It’s like keeping the top on the boiling water that’s about to burst.
In fact they explore a little bit of that in the coming episode.
When we saw Chuck talk to Becky, he went from being pretty chill to getting pissed.
What Chuck are we dealing with in the fall finale?
That’s the first thing he needs to do.
So step 1 is somehow getting in touch with Sam.
We’ve seen a lot of Chuck’s potential endings so far this season.
At this point, has he decided on one ending?
I think he does have an ending.
Before the series ends, do you have anything on your bucket list?
Any character you’d like to share a scene with?
I’ve been able to do so much.
I’ve never worked with Kim Rhodes, that’d be fun to finally have something with her.
I love working with Alex Calvert.
I think Mark Pellegrino’s a genius actor if he could come back.
